Moment resisting frames possess significant ductility and thus are commonly used in
earthquake-resistant designs. However, excessive deformation due to lower stiffness and …

In this study, a replaceable Sandwiched Fuse Damper referred to as SFD is introduced to
enhance the seismic performance of braced frames. The SFD consists of one or several …

This study focused on the performance evaluation of new brace designs that adopted steel
curved dampers with amplified-deformation mechanisms. A series of cyclic load tests on …

One of the newest lateral load-resisting systems is quarter-elliptic-braced steel moment
frames (QEB-MFs). The elliptical geometry of this bracing system not only resolves the …

The paper presents the experimental characterization, the formulation of a numerical model,
and the evaluation, by means of non-linear analyses, of a new friction damper conceived for …

This paper presents a design procedure to evaluate the mechanical characteristics of
hysteretic Energy Dissipation Bracing (EDB) systems for seismic retrofitting of existing …

This paper proposes two novel quasi-X bracing systems to resolve the drawbacks of
concentrically braced frames (CBFs) and enhance their ductility. The seismic performance …

Current design methods for achieving seismic resilience of structures are limited to hazard
levels of service level earthquake, design-based earthquake and maximum considered …

Concentrically braced frames (CBFs) have an excellent performance to the lateral seismic
forces at the time of the mild earthquakes, but they are weak under severe seismic loads due …

Hysteretic steel dampers have been effectively used to improve the seismic performance of
framed buildings by confining the dissipation of seismic energy into sacrifical, replaceable …
